Trying to decide on a color scheme

So i am struggling because the character is suppose to be reminiscent of a poison mushroom but he is a robot. number two is the original color scheme but I'm just not loving it. Looking for some feedback and maybe votes on which color scheme you would pick if you had the option in a game.

I see where you're going with the original color scheme, but maybe the green is too saturated for something based in nature, like a mushroom. I like the green of 5 better. Feels a little more natural, like a mushroom. I like the overall design of 5 better. Green evokes certain emotions and associations, like poison, nature, maybe some mystical presence. Then the brown is kind of neutral, but also natural, like mud or dirt. Then the little pops of a more saturated green kind of give a warning, like a brightly colored poisonous animal. Out of all of these, 5 attracts my eye the most.

Thank you! I agree totally, I've asked a few people and a lot of people said they liked the overall look of 1 but thought that 5 fit the character the best. So I am starting to think I am probably going to go with number 5 and offer other color schemes to players in the game for completion of certain things and for purchase. I will definitely take a look at those resources. Thanks again!

In general good work. Personally I think number 5 suits your motive the most.

But if you want to take it further I would like to make a suggestion. Get on google images search or Pinterest and gather all motives that you associate with poison and robots. Because there is a lot more out there... It is not only green. Make a collection of poisonous mushrooms but don´t forget to include other themes of nature as well (just look at the ball fish.. who is extremly poisonous). How to combine the theme of nature/poison/organic with Robot/metal/mechanic? Brown is associated with earth and dirt. But maybe the Robot as a metalic clean origin color but got rusty over the years. Or his poisonous aspect changed his original material... deformed its texture. What if he is overgrown with moss?

Try to tell the robot´s story through your design.

Doing some research and collecting a solid reference collection helps your creativity to discover new grounds.

Regardless of the colour you choose I would think about making the accent colours a little brighter as in nature when something is poisonous commonly there is a bright warning colour to caution against consumption. Now this is not the case for mushrooms. So the dark blue/green hues and the yellow stand out the most to me.

Thank you so much for your advice! I am going to be adding some texture and stuff to add some more intrigue to the design. I wanted him to maintain a clean and well maintained look because his character is the captain of the "royal guard". however I will be adding a little bit of paint fading around the edges. So I will post when I complete that. I did choose to go with number 5 for the default color scheme by the way. :)

If I may add something, it looks to me like you have shaped his head to be mushroom like, and there are spots on top so Im assuming the top of his head to be the top of a mushroom and the lower part with the two big bolts in to be the "underside" of the mushroom.

If it was me, I would add some sort of texture, be it realistic or stylised, to push the feel of the underside of the mushroom and sell what it is based on. Otherwise it may just get mistaken for some sort of pirate hat inspired head. The texture I am talking about is in the pic below , that sort of "ribbed lines" effect that you always see under mushrooms :
